Hello,
Is there a portable (at least for VC.Net and g++) method to convert text
between
wchar_t and char, using the standard library? I may have missed something
obvious, but the section on codecvt, in Josuttis' "The Standard C++
Library", did not help, and I'm still awaiting delivery of Langer's
"Standard C++ IOStreams and Locales".
Thanks,

In C#, an interface cannot mark any method as static. i'm told the ILASM
supports it but i've never tested that
Two questions. First, why? OK, i've heard the reason about interfaces being
allocated on the stack but that's not a real reason. Which is OK because this
isn't a real question, it's just a complaint dressed up to look like a reason
Second question. If a language doesn't support a fairly obvious feature, one
has to wonder if...

We are having one of those religious debates at work: Interfaces vs
Classes. My take is that Classes give you more flexibility. You can
enforce a contract on the descendant classes by marking methods abstract
(which is all that an interface does). In addition, the classes allow
you to be flexible by adding functionality that child classes inherit.
Or by providing optional functionality via virtual methods.
Now, I understand that...

What is the purpose / benefit of using an interface statement?
It doesn't seem like anything more than a different way to make a class...
(except you can't define any procedures in an interface like you can do in a
class).
I'm obviously missing something...

I am converting (attempting) some vb6 code that makes vast use of interfaces.
One of the major uses is to be able to split out Read-only access to an
obect. Let me give you a simple (contrived) example:
In Project RoObjDefs:
RoPerson.cls file:
Public Property Get FirstName() as String
Public Property Get LastName() as String
<end of file RoPerson.cls>
RoPersons.cls file
Public Function Count() as Integer

Hi,
I wish to convert c++ code written using VC++ 6.0 to the .Net development
environment (Visual Studio 2005).
So far I have copied the code into a new C++ Class Library project and
recompiled it. I got some errors from the linker and had to change the
configuration of the project to use the MFC as a shared dll even though the
code is mostly pure C++ - I guess there must be a reference somewhere.

Hi,
I have been reading on interfaces working on samples I've run across on the
web. For the life of me I cannot seem to grasp them.
It appears to me that interfaces are simply blueprints to a class, that when
implemented, they require the implementing calss to make sure that each of
the properties, functions etc. are handled by the class. (????)
What I am really having a problem with is how they overcome the limitation

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
